spring boot rabbitMq创建队列 配置交换机

首先：代码版本是基于 Spring2.1.12 + Rabbit 整合实现

rabbit：pom

<!-- rabbitmq -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>

rabbit：yml配置

server:
  port: 8600
spring:
  application:
    name: rabbitmq-provider
  rabbitmq:
    host: 192.168.189.131
    port: 5673
    username: admin
    password: admin
    #确认消息已发送到交换机(Exchange)
    publisher-confirms: true
    #确认消息已发送到队列(Queue)
    publisher-returns: true

 

 

1：Direct Exchange 直连交换机

定义:直连类型的交换机与一个队列绑定时，需要指定一个明确的binding key。

路由规则：发现消息到直连类型的交换机时，只有routing key和binding key完全匹配时，绑定的队列才能收到消息。

DirectRabbitConfig

@Configuration
public class DirectRabbitConfig {
    //队列 起名：TestDirectQueue
    @Bean
    public Queue TestDirectQueue() {
        return new Queue("TestDirectQueue",true);
    }

    //Direct交换机 起名：TestDirectExchange
    @Bean
    DirectExchange TestDirectExchange() {
        return new DirectExchange("TestDirectExchange");
    }

    //绑定  将队列和交换机绑定, 并设置用于匹配键：TestDirectRouting
    @Bean
    Binding bindingDirect() {
        return BindingBuilder.bind(TestDirectQueue()).to(TestDirectExchange()).with("TestDirectRouting");
    }

DirectRabbitController

@RestController

    private RabbitTemplate rabbitTemplate;

    @GetMapping("/sendDirectMessage/{message}")
    public void sendDirectMessage(@PathVariable("message") String message){
        String messageId = String.valueOf(UUID.randomUUID());
        String messageData = message;
        String createTime = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        Map<String,Object> map=new HashMap<>();
        map.put("messageId",messageId);
        map.put("messageData",messageData);
        map.put("createTime",createTime);
        rabbitTemplate.convertAndSend("TestDirectExchange", "TestDirectRouting", map);
    }

    @RabbitListener(queues = "TestDirectQueue")
    public void consumerDirectMessage(Map map){
        System.out.println("DirectReceiver消费者收到消息  : " + map.toString());
    }

}

 

2、Topic Exchange 主题交换机

定义：主题类型的交换机与一个队列绑定时，可以指定按模式匹配的routing key。

通配符有两个，*代表匹配一个单词。#代表匹配零个或者多个单词。单词与单词之间用.隔开。

路由规则：发送消息到主题类型的交换机时，routing key符合binding key的模式时，绑定的队列才能收到消息。

TopicRabbitConfig

@Configuration
public class TopicRabbitConfig {
    public final static String man = "topic.man";
    public final static String woman = "topic.woman";

    @Bean
    public Queue firstQueue() {
        return new Queue(TopicRabbitConfig.man);
    }

    @Bean
    public Queue secondQueue() {
        return new Queue(TopicRabbitConfig.woman);
    }

    @Bean
    public TopicExchange exchange() {
        return new TopicExchange("topicExchange");
    }

    //将firstQueue和topicExchange绑定,而且绑定的键值为topic.man
    //这样只要是消息携带的路由键是topic.man,才会分发到该队列
    @Bean
    Binding bindingExchangeMessage() {
        return BindingBuilder.bind(firstQueue()).to(exchange()).with(man);
    }

    //将secondQueue和topicExchange绑定,而且绑定的键值为用上通配路由键规则topic.#
    // 这样只要是消息携带的路由键是以topic.开头,都会分发到该队列
    @Bean
    Binding bindingExchangeMessage2() {
        return BindingBuilder.bind(secondQueue()).to(exchange()).with("topic.#");
    }

}

 

TopicRabbitController

@RestController
public class TopicRabbitController {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @GetMapping("/sendTopicFirst")
    public String sendTopicMessage1() {
        String messageId = String.valueOf(UUID.randomUUID());
        String messageData = "message: M A N ";
        String createTime = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        Map<String, Object> manMap = new HashMap<>();
        manMap.put("messageId", messageId);
        manMap.put("messageData", messageData);
        manMap.put("createTime", createTime);
        rabbitTemplate.convertAndSend("topicExchange", "topic.man", manMap);
        return "ok";
    }

    @GetMapping("/sendTopicSecond")
    public String sendTopicSecond() {
        String messageId = String.valueOf(UUID.randomUUID());
        String messageData = "message: woman is all ";
        String createTime = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        Map<String, Object> womanMap = new HashMap<>();
        womanMap.put("messageId", messageId);
        womanMap.put("messageData", messageData);
        womanMap.put("createTime", createTime);
        rabbitTemplate.convertAndSend("topicExchange", "topic.woman", womanMap);
        return "ok";
    }

    @RabbitListener(queues = "topic.man")
    public void topicManReceiver(Map map){
        System.out.println("topicManReceiver消费者收到消息  : " + map.toString());
    }

    @RabbitListener(queues = "topic.woman")
    public void topicWomenReceiver(Map map){
        System.out.println("topicWomenReceiver消费者收到消息  : " + map.toString());
    }

}

3、Fanout Exchange 广播交换机

定义：广播类型的交换机与一个队列 绑定时，不需要指定binding key。

路由规则：当消息发送到广播类型的交换机时，不需要指定routing key，所有与之绑定的队列都能收到消息。
